den and State of lvlassachusetts, have in-.

vented a new and useful Boiler, of which the :lollowlng 1s a SPQClfiCittlOIl.

My invention relates to improvements in steam or hotnvater boilers for heating buildings, and resides in a certain peculiar arrangement of -manifolds and connecting tubes or pipes, as hereinafter more fully set forth. i

The primary, object of my invention is to produce a boiler for heatingpurposes, which is compact, strong and durable, and so constructed that it has very little radiating'isurface, but insteadpresents or comprisesthe maximum amount of heating surface, hence is highly eflicient and mosteconomical. vIn this last particular it is to be noted that, by decreasing or cutting down the amount of radiating surface to the minimum, the loss of heat is proportionately decreased and the heat conserved for its legitimate purpose, in a boiler of this type, of converting water into steam or heating the water so that the same will circulatethrough a system of hot-water pipes,a and my construction is designed with this particular end in View.

Another object is to provide a steam orhot-water boiler that can be readily repaired in case a break occurs in any part thereof, by replacing the broken orimpa1red part.

till another object isto afford means for easily cleaning outuny boiler.

Other objects and advantageswill appear.

in the course of the following description. b I attain the objects and securethe advantages, of my invention by the means illustrated in the accompanying drawings, in Which- Figure l is a top plan of a boiler, without the casing and'its appurtenances, Which embodiesa practical form of my invention; Fig. 2, a front end elevation of saidboiler, and, Fig. 3, a side elevation of the same, some of the pipes being broken away in this view to expose others on the oppositeside, and the upper portion of the steam drum also being broken off.

Similar, numerals designate similar parts throughout the several views.

Any ordinary and suitable casing, with the fire-pot, grate, and accessories that belong thereto or therewith, is, in practice, provided for the heating elements herein shown and described and which constitute the present invention, but inasmuch as such casing, with the parts and members which are, more or less closely associated therewith, is not a new feature and does not form a part of said mvention, the same is not shown,

as hereinbefore observed. I have, however, represented the new elements as resting on a base plate 1 which is supported by a pair of side base pieces 2, but these members are also old.

' Although I have illustrateda'nd will describe in detail a preferred form ofcon-v structlon of my holler, 1t 1s to be understood that various modifications and changes. in-

the shape, size, construction, and arrangement of some or all of the parts thereof may be made without departing from the nature of the invention.

The boiler shown is provided with a steam drum 3, butthis may be omitted and the boiler used as a hot-water heater.

Passing now to a detailed description of the boiler, it will be observed that the same, comprises two bottom side manifolds 4 and 5, which rest on the plate 1, a series of pipes 6 wh ch rise from said manifold 4, a side manifold 7 mounted on said pipes over said,

manifold 4, aseries of pipes 8 which rise vertically from said manifold 5 and extend over horizontally to said manifold 7, a bottom end manifold 9 which rests on said.

plate, a series of pipes 10 which riselver tically from said manifold 9 and extend horizontally forward, over the horizontal parts, of said pipes 8, to the front end of the boiler, and a manifold 11 at the front ends of said pipes 10. In addition to these parts and members there are other necessary elements which will presently be described.

The pipes 6 openiat the bottom into the top of the manifold and at the topinto the bottom of the manifold 7. The pipes 8 open vat one end into the top of the manifold 5 and at the opposite end into the mani:

fold 7 through the inner sidethereof. The;

pipes 10 open at one end into the top of the manifold 9 and at the other end into the manifold 11 through the back side thereof.

Parallel with the manifold 9 and behind the same is a tubular connection 12, and

vopening into the ends thereof and into the 13, 1% and 15, asis done, provision is made forconveniently obtaining access to the interior of said manifolds for the purpose of cleaning them out, it only beingnecessary to remove said plugs and introduce the proper implement into the manifolds through said connection and pipes.

Rising from the top of the manifold 7 and opening into the same isa tubular connection' 17. The steam drum 3 is mounted on the connection 17 and the latter opens into the bottom of the former. An angular tubular connection 18 opens at one end into the top of the manifold 11 and at the other end into the connection 17. Leading down- Ward from the connection 17 is a tubular connection 19. The connection 19 opens at the top into the connection 17 and at the bottom into the manifolds, through the outer side and just above the floor thereof.

A water-leg 20 may be provided for the protection of the front plate of the casing (not shown). The water-leg 2O communicates at the left-hand end, through a tubular connection 21, with the front end of the manifold 4, and at the opposite end, through a tubular connection 22, with the corresponding end of the manifold 11, below which manifold said water-leg is located on the plate 1. I

The space for the elements of combustion, or for the container therefor, is below the horizontal portions of the pipes 8, in front of the manifold 9 and the vertical portions of the pipes 10, between the manifolds 4 and 5 and the pipes 6 ands or the vertical portions of the latter, and behind the waterleg 20 and the space between that and the manifold 11.

Water isintroduced into the boiler'preferably through or into one of the manifolds 4 or 5, and I have in this case shown an opening 23 in the outer side of the manifold 5 for that purpose-see Fig. 3. When the boiler is complete and set up a Water supply pipe leads to the opening 23 and discharges therethrough.

In order to enhance the heating capacity and decrease the radiating capacity of the 6 boiler a non-combustible sheet, as'shown at around the edges of said sheet before coming into contact with the horizontal portions of the pipes 10. Thus radiation from the i 7 horizontal portions of the pipes 8 is lessened,

and this without taking the heat away from the corresponding portions of the pipes 10.

It will now be seen that, when water is admitted through the opening 23 to the manifold 5, such water W111 enter the other bottom manifolds 9 and 4:,by way of the pipe let, the connection 12 and the pipes 15' and 13, also the water-leg 20, by way of the connection 21, and will rise in said manifolds and water-leg and in the pipes 6 and the vertical portions of the pipes 8 and 10 to the required or desired height. It will be seen, furthermore, that, when this water is heated, the steam generated therefrom will pass from the pipes 6 and 8 to the manifold 7 and from thence, by way of the connection 17, to the drum 3, and from the pipes 10 to the manifold 11 and from thence, by way of the connections 18 and 17, to said drum, while the condensation from said drum passes down through said connection 17 and the connection 19 to the manifold to'be regenerated into steam. The connection 22 opens into the water-leg 20 at a higher level than does the connection 21, wherefore any steam that may be generated in said waterleg rises through said connection 22 into the manifold 11.

' By simply removing the drum 3 and making connection with the hot-water piping system of a building, the boiler is converted fromv asteam-heater into a hot-water heater andoperates assuch. I V

Whether used as one type of heater or the other, the heating capacity of the boiler is the same; that is to say, the heating elements for the water, they being the members which contain the Water or the water and steam,

are heated alike in either case, or have the same area eXposed to the fire-and present the same area. of heated surface to the'water or water and steam in both cases. The boiler, when used in either capacity, possesses the highest efficiency, owing to the particular construction and arrangement as hereinbefore described, which fact will be very apparent and readily appreciable to anyone skilled in the art.

g The major portion of the sheet 2 1 is broken away in the first view soas to permit some of the pipes under said sheet to show in full.
